To all whom it may concern:

Be it known that I, Mioonn SANTAL6,sub- .ject of the King of Spain, residing. at Barcelona, Spain, have invented certain new and useful Improvement in Machines vforTreatin isa specification. V

l y invention relates .to the machines for treating skeins of thread,,that is to say, sub-' mittingthe skeins to the operations of bleaching, dyeing and finishing. Various machines are utilized-in the industrial world for the above said" treatment, though not one has obtained aregular impregnation of, the liquor on the plurality of textile fibers, or if this impregnation is regular, the production of the machine is'small. 1

One of the subject matters of my invention: is to obtain a machine for treating skeins .of-thread, operating the decoc ti on,

bleaching, .dyeing and finishing by which the impregnation'of the skeins is effected with regularity and quickness atthe same Another of the subject mattersconsists in obtaining a machine of this kind, of strong andnsimple building, resistant against deterioration and submitting automatically theskeinshto the various operations as impregnat ion, compression, wringing, airing nor andtreating a great number of skeinsat and'so forth, working in av continuous mana iventime. v y improved machine cons sts ota vat containing the bath-dyeing, bleaching or V finishing bath-into which are placed a plu rality of pairsof rollers in a manner so that theupper roller of each pair is supported by hslidablebearings: In combination with these rollers, comprises the machine two endless parallel'chains, suitably separated and provided with hooks duly distributed thereon, withwhich are engaged the ends of rods 'on whichhan the series of skeins to be treatedQ These 0 ains attachlthe rods in a manner that they always present themselves edgeways in thepath of the direction .of the chain movement and are guided in appropriatemanner for conductingthe skeins through a zigzag ,line until and .acrossthe various pairs of rollers disposed 1n the vat containingjthe. bath for treating the skeins.

There is also provided apair of rubber 192a. Serial'No. 573,735i

compression rollers at, one end of the vat, disposed inorder to extract the, liquor from the-skeins on their leaving the bathj MIGUEL sANrALo, or BARCELONA, sram.

' After having thediquor removed, the Q skeins, are exposed to. the actionotthe air J for their-oxidation, if it is a questionof. dyeing, or for their hardening 'and drying :if it is a questionot finishing the same. i r

.The exposition to the'action of the air ended, the skeins .are withdrawn from the machine to be substituted .for new ones or areleft yet on the chain to submit, then to a second passing in the machine.

' .The invention Will be fully described ini accordance with the accompanying drawings showing vention;

a machine whichembodies my inv v v v v v Fig. i as side elevation oftheniachinefj Fig. 2 is. a vertical longitudinal section" along the line. II-II of Fig. :3; I v Fig. 3'is a verticalcross sectionalo-ng the 'line'I-IIIII, of the Fig. 1;.

with which the skeins have to be treated.- Inside the vat Qithereare positioned pairs of rollers 8, 9, suitablydistributedlengthwise of the vat. Each pair of rollers 8, 9,,

lower roller 9'is supported infixe'd hearings andnthe axle of, theup'per roller 8 is'sup- .porte'd in bearingsIO, slidably ni unted' inQ A The machine consists'of 'a vat contain- ,ing'the dyeing, bleaching or finishing. bath is supported by bearings 4. constructed in i the known manner whereinthe axle of the the bearings 4 and moved by means of a small screw-threaded spindlegwhicih passes through the column 7 of the supportand f terminates in the bevel pinions 11 which engage with the pinions 11" mounted'on'jthe,

shaft 13. In order to, impartmovementfto the upper hearings on both sides of the ma chine the shaft '13 'is provided with aihand [wheel 12. In this way thepressure'which the upper rollers 8 exerciseupon the lower Q. rollers 9 is regulated and consequently the,

pressure upon the skeins 39 subjected to treatment. ff i At the extreme end of the vat vQthere are arranged outside of the bath two compressor rollers 14', 15'. The axle 160i the roller 14;

is supported Zin fixedibearingsfandthe axle of roller 15 is supported In a movablebearing 26 the position of which can be adjusted by means oftheispindlef27 and fly'-wheel 2 S p with interposition of a helicoidal spring 29 so as to be able to graduate in an elastic manner the pressure which the roller 15 has to exert upon the roller 14.

These rollers 14:, 15, are situated immediately above the bath, so that the wringing out of the skeins takes place when they are in a vertical position and before the liquid of the bath has had time to become altered or oxidized. Consequently the liquid when wrung out again falls back into the bath and is used afresh. If necessary a casing maybe arranged to surround the rollers 14, 15, so as to isolate the skeins from contact with the air as far as possible whilst they are being wrung out.

There is also combined with the machine a pair of chains represented in the drawing by the lines 3, 3'. These chains are at a distance corresponding to the width of the ma chine and have hooks suitably distributed thereon, with which are engaged the ends of rods 38 which guide the series of skeins 39 to be treated. These chains are guided by pulleys or chain wheels 20 so that they change their direction, passing from the horizontal to the vertical, and the rods 38 which contain the skeins 39 are so attached to the chains that they always present themselves edgeways in the path of the direction of movement. However when the chains 3, 3' change their direction the rods 38 make part of a turn thus automatically changing the points of contact of the skeins 39 with the rods 38 and thus causing the threads to be uniformly impregnated over their whole length.

r The pulleys or wheels 20 do not communicate movement to the chains 3, 3 but they merely serve as a guide and, to this end, they are loosely mounted upon their respective axles. The guide wheels 40 stretch the chains in the manner already known. and on passing by these guide wheels, the rods 38 can be removed from the chains together with the treated skeins and fresh rods with skeins may be attached to the chains. Nevertheless in practice it is preferable to prolong the path which the chains follow and to arrange a point for removing the rods with the skeins already treated and another for adjusting the rods loaded with fresh skeins.

The rods provided with skeins follow the movement indicated by the arrows 19 and pass over the roller 21 which guides them to the rollers 8, 9. These latter rollers cause the rods to make successive zigzag turns up to the guide roller 22 which directs them to the wringing out rollers 14:, 15. This operation is repeated several times if necessary and as, within the same bath, the chains change their direction several times the rods 18 also change their position thus altering the points of contact of the rods with the skeins and thus allowing of a thorough mitted to the axle 24 of the pulley 25 which actuates the chain 3 on one side of the machine and through the gearing 6 the movement is transmitted to the axle 24 of the pulley 25 which moves the chain 3 on the opposite side of the machine.

At thevopposite end of the axle 16 there is y a chain pulley 30 which by means of a chain 31 transmits power to a pulley 32 mounted on the axle 33 supported at this end by a bearing 34. At this end the axle 33 carries a toothed or gear wheel 35 which by means of intermediate pinions 36 imparts a rotary movement to wheels 37 mounted on the axles of the rollers 9.

The number of teeth on the wheels 30, 32, is so calculated that the rollers 8,9 rotates with a peripheral velocity slightly greater than that which the wheels 25, 25 communicate to the chains 3, 3. The result of this is that the skeins 29 on passing between the rollers 8, 9 are fedv slightly forward of the rod 38 which guides them and, consequently, the fold of the skein fails to come into contact with the edge of the rod and the liquid in the bath thereby penetrates into the fold of the skein.
